Disk Management problem (in Windows) creating space to install Ubuntu

view full story

http://askubuntu.com – I tried to do a second partition on my PC and now on the disk management is saying that is in simple volume. I want to change it back to normal (with the blue color). I was trying to do the second partition because I want to install Ubuntu on it. now i don't know how to get the disk management back to normal, and the color of my C:, E:, and E: are yellow. Picture: http://i.imgur.com/oiKLI.png I read on a forum that if my disk is dynamic I cannot boot into Windows 7 again after installing Ubuntu. I am scared things may already be broken in this way--what do i do now? (HowTos)
